Southland Sizzles, With Record High of 110 Posted in the Valley
Temperatures soared to record levels in the San Fernando and Simi valleys Monday, with a top reading of 110 degrees at Chatsworth. Forecasters say it will be just about as hot today.
Monday’s high in Chatsworth broke the record for the date there of 105, set in 1978. It was 108 Monday in Simi Valley, 4 degrees above the record for the date, set in 1978, and it was 108 at Pierce College, one degree above the record there, set in 1949.
Other readings Monday included 108 at the Pomona Fairplex, 107 in Northridge and Van Nuys, 103 in Burbank, 102 in Monrovia and 101 in Pasadena and Thousand Oaks.
It was significantly cooler closer to the coast.
Readings of 91 were taken in downtown Los Angeles, 81 in Venice and 72 at the pier in Santa Monica.
The National Weather Service said the hot valley weather is the result of a ridge of high pressure that is blocking the onshore flow of cool, moist air from the Pacific.
Forecasters said this ridge will weaken this afternoon, but only slightly, and temperatures in the valleys will remain above 100 through Wednesday.
The onshore flow should start returning Thursday, but high temperatures are expected to reach the 90s in the valleys through the weekend.
